Parallel (geometry)

Wikipedia open wikipedia design.

We can see that lines a and b are parallel because the angles between the lines and an intersecting line are the same.

Parallel is a term in geometry and in everyday life that refers to a property of lines or planes. Parallel lines or planes are next to each other, but never touch each other. This means they never intersect at any points. The slopes of parallel lines are always equal.

Even if these two line segments were extended to infinity, there would never be a point of intersection between the two of them.
